PAUL DELAHAY
Cyclic voltammetry became one of the most widely used electroanalytical techniques. Instruments in which several triangular sweeps were applied were developed by Sevcik and Delahay. Among techniques using controlled current and measuring voltage or its function, chronopotentiometry was introduced in the fifties by Delahay.
Both the principles and theory of most of electroanalytical techniques were summarized in the monograph by Delahay (P. Delahay, New Instrumental Methods in Electrochemistry, Interscience Publ., New York, 1954), which became the textbook used in education of the new generation of American electrochemists (I have learned electrochemistry from the Russian translation of this book).
